> plot(Data$residuals, type="p", main="Index Plot", ylab="Residuals", pch=19) > abline(h=0) The plot appears in R in the graphics device. To plot the residuals against the predictor ACT, you can use the command: > plot(Data$ACT, Data$residuals, main="Residuals vs. Predictor", xlab="ACT Test Score", ylab="Residuals", pch=19) The plot will appear in the R interface on the graphics device.

Data files should most easily be set up as text files with rows as cases and columns as variables. Datasets for this course will be found in this format on the course web site. Save them to a text file and use read.table to read them into R as data frames. This will require a complete path to the file's location.

In a data set with a strong linear correlation, the points in the scatter plot approximate a line. Turn on Show least-squares fit line. The . least-squares fit line. is the “best-fit” line, or the line that most closely “fits” the shape of the data. When r = 1, how are the points in the scatter plot …

He first wants to plot the data with the Michaelis-Menten method (Michaelis and Menten 1913) and deduct values for the parameters of the equation. Michaelis and Menten showed that the rate of an enzyme-catalyzed reaction is proportional to the concentration of the enzyme–substrate complex predicted by the Michaelis–Menten equation.
